WILD-OATS ATTACHMENT FOR FANNING MILLS.

Specification of-Letters Patent. .Patented Jan. 24, 1922.

Application filed July 22, 1920. Serial No. 398,084.

To all whom it concern."

Be it known that we, EDWA D GRIMsRUD and ToneJonN T. Tnrrnw, citizens of the United States, residing at'lVild-rose, in the count; of lVilliams, State of North Dakota, have invented a new and useful lVild-Oats Attachment for Fanning Mills, of which the following is a specification.

This vinventiongai'ms to vprovide novel means whereby wild oats may be removed from grain, after the grain has passed through a fanning mill.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to'which the invention appertains.

lllith the above and other objects in view which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, itbeing understood that, within the scope of what is claimed, changesin the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

'In the accompanying drawings 2 Figure 1 shows in side elevation, a device constructed in accordance with the invention; parts being broken away; Figure 2 is a top plan; Figure 3 is an end elevation; and Figure 4 is a longitudinal sectional detail showing a portion of the belt;

In carrying out the invention there is pro vided a frame including posts 1 which may be part of a fanning mill 2 having a discharge chute 3, the posts 1 being united by a beam 1. Inclined supports 5 are attached to the posts 1. BracesG extend between the supports 5 and the posts 1. A shaft 7 is r mounted in the supports 5 near to the lower ends thereof, the shafticarrying a pulley 8 located between the supports. A shaft 9 is journaled for rotation in the supports 5 adjacent to the upper ends thereof, a pulley 10 being secured to the shaft 9 to rotate therewith, the pulley 10 being of consider ably larger diameter than the'pulley 8. About the pulleys 8 and 10 is extended a belt 11, the belt operating between the supports 5. The belt 11 comprises abody 12 made of cotton flannel orsome other material having a map) The body 12 of the belt is reinforced by edge bindersl l which may be U-shape in cross section. Transverse reinforcements 15 extend across the body 12 .of the belt 11, the ends of the reinforcements 15 being engaged between one flange of each of the binders 1 1 and the body 12 a detail which will be understood readily when Figure 4 of the drawings is examined. Adjacent to the pulley 10, a pronounced angle is fashioned in the upper run of the belt 11.

The means for forming the angle in the upper run of the belt 11 comprises a pair of arms 16 pivoted at their upper ends, as shown at 17 to the members 6. Braces 18 are provided, the lower ends of the braces 18 being pivoted at 19 to the lower ends of the arms 16. The braces 18 are provided with seats 20 adapted to be engaged with projections on the members 6. The arms 16 are supplied with seats 22, in any of which an axle 23 may be received, the axle 23 carrying rollers 24 engaging the edge binders 14 of the belt 11. Clearly, the axle 23, may beshifted with respect to the verti veyor belt 11 thus may be tightened, and the angle may be fashioned in the upper run of the conveyor belt. 7 Y

' A pulley 25 18 secured to one end of the shaft 9 and is engaged by a driving bel't'26 passed around a wheel 27 on one of the posts 1, the belt being passed around an idler 28 on the said post. The wheel 27 is the driving element, and, ordinarily, constitutes a part of the fanning mill 2. p

The numeral 29 denotes a transverse rod mounted at its ends in the supports Links 30 are mounted to swing on the rod 29, the lower ends of the links being pivoted to the sides of a receiver 31, the intake end of which is disposed relatively near to the angle whichexists in the upper run of the conveyor belt 11. The rear end of the receiver 31 is slidably mounted upon afchute 32 carried by one of the supports 5 and discharging laterally beyond the frame work of the machine, as indicated in Figure 3 of the drawings. The receiver 31 discharges into the chute 32. The forward ends of pitmen 33 are pivoted to the sides of the receiver 31, the forward ends of the pitmen being supplied with straps 34 cooperating with eccentrics 35 on the shaft 9.

Arms 36 are attached to the supports 5. The numeral 37 denotes a scraper located.

' the lower run of the belt 11.

37 is provided intermediate'its upper and lower edges with pivot elements 38 mounted to rock in the forward ends of the ,arm's'36. At its ends and adjacent to its lower edge, the scraper 37 is supplied with lateral e3:- tensions 39 connected with the supports 5 byadjusting devices 4-0, of any desired sort, such turn buckles. f

' In practical operation, the wheat is discharged ltrom the fanning mill 2 through the chute 3 on the upper run of the belt 11. Practically all of the wheat will slide off the upper run of the belt 11, in the direction of the arrow A in Figure 1. The wild oats, which have a considerable burr, will a adhere to thebelt '11, because thebody 12 I on the shaft 9. The grain whichthus is of the belt is provided with a pronounced nap. The wild oats will be carried up wardly and forwardly, on the upper run of the belt and will accumulate'in the angle which is formed in the upper run of the belt.- Should any small quantity of the grain be -carried up, along with the wild oats, the grain will tend to work out of iv the wild oats and to fall into the receiver. 31. Areciprocating movement is iinpartedto the receiver 31, owing to theipresence of'the pitmen 33 and the. eccentrics 35 segregated from the wild oats, passes from the receiver 31 into the chute 32, and lfrom the chute, out of the machine.

"The wild oats are carried upwardly around the pulley 1O, by the belt 11, and come ultimately into .contact with the scraper 37, the oats being removed from the belt 11. ;The position of the Working end of the scraper 37 with respect to the belt ll and the periphery of the pulley 10 may, of course be adjusted through the instru- The scraper I mediate its ends on the elements'38.
